Continuation of application Serial 110,199,349, led October 23, 1917,whioh was a division of application No. 101,457, led June 3, 1916. Thisapplication filed May 26, 1919. Serial No. 300,006.

Be it known hat I, PERcIvAL S. Tron, a citizen of the nited States,having residence in the city of Detroit, county of Wayne, and- State ofMichigan, have invented certain new and useful Improvements in Methodsof Furnishing vExplosive Mixture to Intermal-'Combustion Engines, ofwhich the` leading to theengine intake and referred toy following is aspecification, reference being lhad to the accompanying drawings,forming a part thereof.

This application is a continuation of my application, Serial No.199,349, filed October 23, 1917, and covering subject matter divided outof my application, Serial N o. 101,457, which was filed June 3, 1916.

The purpose of. this invention is to provide an improved methodof'furnishing explosive mixture to internal combustion engines. Itconsists in the method or process described consisting of the severalsteps and means set out inthe specifications and illustrated in thedrawings, as indicated inthe claims;

In the drawings: l i V Figure 1 is an elevation of a portion of aninternal combustion engine having a plurality of cylinders, the artsbeingr broken away in part on the line, K-A, inl Fig. 2, and shown insections to illustrate the internal construction. i

Fig. 2 is a detail plan view showing mainly the exhaust manifoldgthesame being broken away in part on the line B-B, on Fig. 1.

a, a, indicate the cylinders o f an internal combustion engine.` b, b,indicate the branches of the pipe containing the passages in the claimsas'the .engine intake passage. c is a contracted portion of theatmosphere inlet passage, c, vand leads to the intake manifold. d, isaliquid fuel discharge noz' zle or terminal, offa 'liquid fuel inlet pipevwhichvis adapted to constitute a spraying nozzle'for s piaying ordispersing the-hydrocarbon'fuel discharged from it, said nozzle beingprovided for this pur se with a co-axially-situated minor air in etpipe, d. The spraying nozzle which has both the interior a'nd theexterior elements,-that is, the nozzle, d, and the co-axially-situatedminor Vair inlet pipe, d,'is positioned with its discharge end extendinginto the contracted portion, c', of t e main atmosphere inlet passage,c. e is t e exhaust manifold; this is located directly vabove the intakemanifold the current of issuing vapor.

in the construction shown. f is a casting forming a chamber closed atits upper end and open at its lower end, and said casting fitting intothe intake manifold, b, so that its interior is open tothe interior ofsaid manifold, and is axially in line with the contracted portion, c, ofthe atmosphere inlet, c. Thecasting, f, extends upward into the exhaustmanifold, e, and is provided with 'i f, and is caused to strike againstthe interior surface of said casting and the ribs, f2, in4 a very finelydivided form or mist, so that it is immediately vaporized and theparticles 3()I thus do not come into a spheroidal state.

The vapor expands'and flows into the manifold, b, b, and is mixed withlthe incoming air, and gives up its latent heat in part to the air,\sothat itis condensed into a mist 315 which remains suspended in the airand is readily re-evaporated in the cylinders.

Because the amount of liquid discharged through the nozzle, d, isproportional to the quantlty of air passing, and because the llquid isprojected into the chamber inclosed by the casting, f, and isimmediately vaporized therein, the amount of vapor issuing from theinterior of said casting in the pass# ing air will be proportional tosuchair, so that the air will be'heated to about the same degree underall conditions of working of the engine.

The insensible heat of the issuing vapor is largely used to heat thespraying liquid en- 100 terme the chamber in the cas-ting, f,

against I claim 1. The method of furnishing 'an explosive mixture to aninternal combustion engine 105 -whichconsists in first producing by thesuction of the engine africh mixture of liquid fuel and air atsubstantially normal temperature byaspiration; and next heatingV suchrich mixture to the vaporizing point 110 of the liquid fuel particles,and linally, thoroughly intermixing suchvaporized mixture with anadditional quantity of air at a lower temperature.

2. The method of supplying an explosive mixture to an internalcombustion engine, which consists in drawing in by the suction of theengine a charge oi hydrocarbon fuel and a limited charge of air atsubstantially normal temperature in such juxtaposition thereto as tocause intermixture of the hydrocarbon fuel and subh limited air supply;next, continuing the suction of the engine upon the rich mixture, andthereby vcausing it to be injected into a chamber heated above thevaporizing point of the hydrocarbon;

- next, engaging it on its emergence from the hea-ted chamber in and byan air current also drawn in by thesuction of the engine at a lowertemperature.

3. The method oi supplying an explosive hydrocarbon mixture to aninternal combustion engine, which consists in drawing in by the suctionof the engine, a liquid hydrocarbon supply, and simultaneously andcontiguously by the same suction drawing in a limited air supply atsubstantially normal temperaturefor mixture with said hydrocarbon liquidsupply; next, causing said mixture to be injected, by the momentum ofthe in-drawing movement into a chamber heated above the vaporizing pointof the hydrocarbon, and to be discharged from said chamber by the samepath by which it entered into a greater air current drawn in by thesuction of the engine, Jfor admixture with the air thereof. p

In testimony whereof, I have hereunto set my hand at Chicago, Illinois,this 16th day of May, 1919.
